The coastlines of Kalimdor and the Eastern Kingdoms shifted, flooding some old lands and exposing new ones. Whole parts of the world, like Thousand Needles and a large chunk of Tanaris, ended up underwater. In some cases, tidal waves caused by the Cataclysm flooded or destroyed coastal settlements like Auberdine, Rut'theran Village, and Feathermoon Stronghold, forcing their residents to relocate — usually inland. Even far from the coast, fires, avalanches and lava eruptions changed some areas beyond recognition. The Barrens was split into two.
The tectonic shifts blocked some old routes, like the one between Badlands and Loch Modan, and opened some new ones through previously impassable mountains. The Cataclysm also damaged an ancient titan device previously hiding the Uldum complex, exposing access to it from Tanaris. The island of Kul Tiras was shifted out to sea by shifting tectonic plates. Zandalar has been severely crippled.
The Cataclysm brought the Elemental Plane closer to Azeroth, bringing the world in direct conflict with the elemental lords — including , who, upon his return, assaulted Nordrassil, prompting to organize a defense of Mount Hyjal again.
The goblin island of Kezan and the self-isolated nation of Gilneas suffered greatly from natural disasters, leading directly to events that affected the existing balance between the Horde and the Alliance respectively, redrawing the political map of the world. Mount Kajaro on Kezan erupted, forcing an evacuation by the goblins. Earthquakes damaged the Greymane Wall that had protected Gilneas by land and a coral reef that protected them by sea, opening them up to invasion by the Forsaken and the rest of the Horde. Large chunks of of the lands near the sea also ended up underwater in a manner of seconds.
During his last battle, Deathwing tried to summon the final Cataclysm. After the Aspect's death, Thrall concluded that the Cataclysm is over.
